GREAT NEWS! @Brooko @felixgrill !!!
so it turns out after a LOT of googling, that this issue is similar to the first-gen X3 on linux. here's what i did (i dont remember the order):
*i stuck a mechanical pencil in the reset button, then i factory resetted the DAP through options, turned off the idle off and sleep options on the DAP, and set usb mode to DAC (all done while unplugged from the computer)
*shut down the computer
*plugged in DAP
*turned on computer (everything booted fine no problem, could get passed login screen and everything
*went under pulseaudio sound settings and all my devices were listed
*went into deadbeef and enabled alsa passthrough w/ no resampling "direct hardware FiiO X3 no conversions"
*hit play
*??????
*profit!
it should work for you @felixgrill. i wish i didnt have to deal with this crap, but in the end it did work. i hope this helps any other linux users that run into issues. ITS DOABLE!
thanks for the tip! very glad to hear it works for you.
I think I somehow broke something with pulse. Will do a clean install later today and try again. For now, I kicked out pulseaudio and use alsa instead, that works just fine. but need to find a way to get cantata/mpd back for DSD support.
can you send me the link of the page you found with this information?
If I'd be any near you I'd invite you for a beer mate. guess you're not from Austria...
